Introduction: How to Make Plastic Bottle Cap Nozzles

I show how to modify a plastic bottle cap into a nozzle. The plastic bottle cap is heated up over a candle until it becomes malleable and can stretch. A skewer is then pushed into the bottom of the cap creating a funnel shape sticking out. It is then held for a few seconds until it solidifies and is dipped in water. The tip can be cut off higher or lower on the funnel creating the desired diameter of the hole. This is a very easy project and only requires plastic bottle caps, pliers, wood/metal skewer, scissors, and a candle or lighter. It can be used as a cap for glue, sauce, cooking oil, icing, etc.

Step 1: Materials

- Pliers

- Scissors

- Wood skewer/Metal skewer

- Plastic bottle lids

- Candle/Lighter

That's the same method used for more than 20 years in Australia for making holes in the side of plastic bottles: apply a flame to a spot and when it gets soft apply air pressure into the bottle via your mouth to its mouth. The soft plastic will balloon out and pop. One can then quickly shove in a tube for a pouring spout or whatever and the plastic cools and hardens around it forming a waterproof seal.

Awesome idea. A while back I had the idea to use bottle caps to make little containers for keeping my paints wet and it worked perfectly. Your idea would be great for larger mixes, paint mediums, and glues. I wonder if it's possible to create a cap for them. I'll have to give it a try.

Excellent idea! We used to do something similar to this in school with hollow glass rods and a blow torch to make eye droppers.
